The size of the wave is one variable which determines the overall quality of the virtual acoustic instrument. All things being equal, the larger the sample the better the instrument emulates the real thing. As you know serious composers or screen writers either use the real instrument or those (virtual instruments) in the GB range. They usually do not use, e.g., pianos found in workstations or arranger keyboards but rather something like Bardstown's Bosendorfer 290, etc.

I am certain for live performances most virtual instruments found in workstations or arrangers are sufficient
